MULTI-SCALE NEARSHORE & BEACH CHANGES

R. Ostrowski, Z. Pruszak, R.B. Zeidler

Abstract

Empirical orthogonal functions in one- and two-dimensional formulation are employed to identify the variability of longshore and cross-shore features in different scales, ranging from days to years. The prototype topographic data was measured in coastal zones of the Baltic and Black Seas. Conspicuous features such as berms, bars, salients and. cusps can be identified through e->£. Temporal variation of cross-shore transport is reflected in c21 and ea^ while linkage of c;(1 to coastal factors remains unspecified.
